Using long preambles on an Atheros WG311T wireless card

[Christophe Ramon]

Dear all

I'm running hostapd on a FreeBSD 6.1 server and an Atheros WG311T wireless
card.

ath0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 2290
        inet6 fe80::214:6cff:fe72:a9fa%ath0 prefixlen 64 scopeid 0x3
        inet 10.1.0.1 netmask 0xffffff00 broadcast 10.1.0.255
        ether 00:14:6c:72:a9:fa
        media: IEEE 802.11 Wireless Ethernet autoselect mode 11b <hostap>
        status: associated

        txpowmax 37 protmode CTS burst dtimperiod 1 bintval 100

I am desperately trying to switch the wireless card to use long preambles
instead of Short ones (to be able to avoid the many frames lost between
the WG311T card and an iPod Touch):

 SSID            BSSID              CHAN RATE   S:N     INT CAPS
freebsdap       00:14:6c:72:a9:fa   11   11M    29:0    100 EPS  RSN

Didn't find any way so far ! Any suggestion would be appreciated.

Thanks.
